STAPLE-DRIVER.

SPECIFICATION forming part of Letters Patent No. 746,549, dated December 8, 1903. Application filed August 8, 1903. Serial No. 168,823. (No model.)

To all whom it may concern:

Be it known-that we, THOMAS B. MODLIN and WILLIAM H. BUHL, citizens of the United States, residing at l-Iurdland, in the county of Knox and Stateof Missouri, have invented a new and useful Staple-Driver, of which the following is a specification.

This invention relates to a device for constructing wire fences, and it is particularly designed for use in connection with stapling the line-wires to the posts and stays.

One of the principal objects of the invention is to provide a device of the class specified which will consist of a minimum number of parts and one which can be easily assemble'd.

A further object of the invention is to provide a cheap, durable, and efficient implement or tool which will materially lessen the labor of constructing the fence.

Further objects and advantages of the invention will be specifically described hereinafter, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of the implement complete. Fig. 2 is a longitudinal view of the sleeve. Fig. 3 is an end view of the sleeve, and Fig. 4 is a perspective view of the driving member.

One of the members is termed the driving member, and it consists of a shank 1, with a reduced approximately rectangular staple-contacting portion 2 at one end, with a concavity 3 terminally disposed and conforming to the arched configuration of the staple. On the opposite end the shank is a weighted head 4., which also serves as a ban-,.

dle to be grasped, so as to assist in driving the staple into the post or stay.

The member 5 is sleeved upon the shank and is provided with a bore 6, in which the shank 1 is adapted to reciprocate to drive the tacting end of which is enlarged to impart additional strength thereto.

10 designates an annulus exteriorly disposed upon the sleeve to form a stop for the hand of the operator.

Within the bore of the sleeve 5 is a staggered groove which comprises two parallel longitudinal portions 11 and 12 on opposite sides of the sleeve and connected by a transverse groove 13. The portion 11 of the groove terminates at one end at one terminal of the sleeve, while the other portion, 12,-terminates within the sleeve. This groove is for the reception of a lug or projection 14, carried by the shank 1, and said lug can be introduced into the groove at .the entrance end, and by turning the shank so that the lug will' pass along the transverse portion 13 the lug can enter the portion 12, in which it is adapted to be manually reciprocated.

The driving member will be limited in its movement at one end by contact with the shoulders of the sleeve, and the return movement will be limited by a Wall of-the intermediate portion 13 ofthe groove.

The notches 15 and 16 in the end of the sleeve are for the purpose of permitting the end of the sleeve to straddle and hold the wire so that the staples can easily be held in the proper position during the act of stapling.

We claim 1. A wire-stapling implement for tences, comprising two members, oneof which is a reciprocating member and the other a sleeved member, the sleevedmember being provided with an interior longitudinal guiding-groove extending toward the point of the tool and having a transverse portion communicating with a longitudinal introducing portion, and a rigid projection on the reciprocating memher and working in the guiding-groove, the Y the other groove portion and providing a our own we have hereto affixed our signaguide means, a projection on the reciprocattures in the presence of two witnesses. ing member, and freely movable in the guidel groove portion, the reciprocating movement 5 of said projection being limited at one end by the end wall of the guide-groove and at the Witnesses: other by the wall of the transverse portion. THOMAS POWER,

In testimony that we claim the foregoing as CHRIS. BECK.
